Changing Synchronization and Heartbeat Channels

To change synchronization or heartbeat channels or replace a NIC, follow the next steps:

1. Launch StarWind Management Console and connect to the first StarWind HA partner node.

2. Right-click the required HA device and click Replication Node Interfaces on the shortcut menu.
